Abstract :
The proposed quasi-analytical method undertakes the shaping of a desired footprint as a composition of several phi-symmetric circular Taylor patterns exhibiting flat-topped beams. The final pattern is obtained after sampling the circular aperture that is obtained for rectangular-grid planar arrays. A triangular-shaped footprint and a footprint of continental Europe, radiated by planar arrays with moderate and large numbers of elements, show the technique´s performance.
